IMHO. Here I am. [flag@NewLuxor flag]$uname -a FreeBSD NewLuxor.localdomain 4.2-BETA FreeBSD 4.2-BETA #0: Tue Oct 31 17:43:34 CET 2000 flag@NewLuxor.localdomain:/usr/obj/usr/src/sys/NEWLUXOR i386 [flag@NewLuxor flag]$ I posted some times ago a message about my ppp problem with my dial-up connection (the msg was "Random net errors" or something similar but, for better result, you can try searching for msg coming from me). These problem appeared after a make world (CFLAGS=COPTFLAGS=-O2 -march=k6 -mcpu=k6 -pipe). I saw oddity with my dial-up connection, I'll try to explain: every time I connected to my ISP the connection-phase was ok (the log showed me no errors). But when I tried seeing the web-pages I got a lot of time-out errors, like the site was down/unreachable. So I rebooted in Windows and all was fine (the site was up&operative). So I booted under Linux/BeOS/QNX and all give me the same response: the connection was fine. But every time I used FreeBSD I got that random errors. And the major strangeness is that this error was not really random. For example the site x.mame.net wasn't accesible for 99% of my try, but seldom It worked. Other sites worked well every time. The Mirabilis server (icq server) worked only in the pair days and so on.... This problem disappeared when I rebuilded world using only "-O -march=k6 -pipe". So if you need any other info, I'm here Paolo p.s. Apologize me for my bad english..=P p.p.s. Can we change the subject of the email?
